The SIL40C Series is a new high density open frame non-isolated converter for space-sensitive
applications. Each model has a wide input range (10.2 Vdc to 13.8 Vdc) and offer a wide
0.9 Vdc to 5.0 Vdc output voltage range with a 40 A load. An external resistor adjusts the
output voltage from its pre-set value of 0.9 V to any value up to 5 V. Typical efficiencies are
92% at full load conditions. The SIL40C series offers remote ON/OFF and overcurrent
protection as standard. With full international safety approval including EN60950 and
UL/cUL60950
, the SIL40C reduces compliance costs and time to market.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
